介绍了采用优化通风系统、高水材料巷帮充填沿空留尾巷、底板穿层钻孔和顶板高位巷道抽放等措施综合治理瓦斯的技术内容和效果。通过综合治理,基本消除了高瓦斯高产炮采工作面瓦斯超限现象,月产量保持在40000t 以上,并创造了月产62192t 的全国炮采最高纪录。
This paper introduces the technical contents and effects of comprehensive treatment of gas using such measures as optimizing ventilation system, laneway filling with high water materials, tailing lane along the sky, drilling through the floor through strata, and high-level roadway draining of the roof. Through comprehensive management, the gas overrun phenomenon of the high-gas and high-output artillery mining face was basically eliminated, and the monthly output was maintained at above 40,000 t, creating a record high of 62,192 t per month nationwide.
